What kind of friction allows you to walk without slipping?
Alternately, as we step: sliding, or dynamic friction; static friction; sliding friction again. Sequence repeats with each step.
Why does a concrete path produce greater friction then a lino floor?
A concrete path produces greater friction that a linoleum floor because its surface is rougher. This allows more surface area to contact an object moving along the path.
Why is it important to have cartilage around the end of bone?
Allows joints to move smoothly and without friction.
What is the difference in a grass trimmer with a clutch and one without a clutch?
A trimmer With a clutch allows the head to stop spinning when you let off the gas, and a NON clutch keeps spinning,
How is friction good?
Friction is good for two reasons, both are related. 1) Friction allows your car to stay on the road. Bigger tire surface translates to more friction=better handling. Also 2) friction stops your car (brakes). The bigger the contact surface from the tire (the tire touching the road) and the better the braking system (drum brakes or disk brakes), the quicker your car will stop.
Why it is possible to write on rough black board?
It is easy to write on a rough blackboard. The friction between the chalk and the rough surface is what allows the chalk to leave behind the chalk dust that we see. Actually it would impossible to write on a theoretically smooth blackboard. Without the friction, the chalk would not leave any residue!
How is friction useful in everyday life?
It helps clean clothes in the washer. Friction is important in all aspects of life. Friction is a contact force caused by interactions at the molecular level. If friction was not present, any object accelerated on a flat surface would continue to move in that direction infinitely, or until it met an obstruction on that surface. Similarly, without friction, locomotion (moving) would not be possible because we would have no way of establishing contact with any surface. Our feet (or anything, for that matter) would not "grip" any surface, but rather accelerate across it in the direction of the muscle movement. Situations like these do not arise because there is no such thing as a completely frictionless surface. Friction, in terms of how it is used on Earth, can be very helpful in preventing motion. For example, it is the force of friction that allows brake pads to squeeze the rotors of a car's wheel, thus converting the kinetic energy of the moving vehicle into thermal energy, slowing it down.
How does lubricating machinery-such as the chain on your bike reduce friction?
The surface tension between the metal on your chain pieces is high. The surface tension is low on lubricants like oil or graphite so putting them between moving surfaces provides a opposing surface for both materials that has a low friction.
What is the helpful effect of friction?
It enables us to move: without friction we would be in a permanent skid. It allows us to hold things: they would just slide away.
Why standing friction is greater than sliding friction?
Starting, or static, friction is greater than sliding friction in general. Static friction requires force to be overcome as the object rests on a surface due to its roughness. The roughness is a bunch of small contact points under high stress that resists motion; once this resistance is overcome, the object moves and its velocity allows the surface to glide over the rough spots more easily . This sliding friction is thus a little lower than static friction
Why a wheel cannot roll without friction?
Walking would not be impossible, but it would be likened to trying to walk on ice. Friction opposes movement, which can also be translated into traction. The more friction, the more of an opposing force the object will feel. Since ice has no friction, slipping and sliding is a problem to deal with. But since the majority of ground material on Earth has some type of friction, the opposing force that it provides also allows the feet to remain firmly planted on the ground rather than slipping out from underneath.
What physics is applied in bowling?
When you are playing bowling you exert energy by swaying your hands as you role the bowling ball to the bowling pin.The physics applied is Kinematics :) ====================== We call it rolling without slipping. Its an extraordinary motion which friction allows us to produce. Normally if we try to roll a circular object without friction it wont roll but it would slip on the surface. But on having friction we have a couple in action which is now able to produce torque. This torque helps the object to move forward.
